The public display is "proof of our ongoing product offensive," incoming Peugeot brand boss Maxime Picat said in a statement.

The troubled manufacturer has seen its stock price fall 57 percent since late February, when it announced an alliance with General Motors to share parts and cut costs.

"We're adding emotion to our brand and will emerge stronger from this crisis," said Picat.

The Onyx concept uses a wide range of natural and repurposed products, including copper, carbon fiber, compressed-newspaper “wood” and a one-piece felt interior.

The 2012 Paris motor show—or Mondial de l'Automobile, as it is officially known––will take place Sept. 27 through Oct. 14. It occurs every two years, alternating with the Frankfurt motor show in Germany. Paris is a showcase for the latest in design, but automakers will also be showing off their latest concept cars, green cars and supercars.
